Yeah the article is pretty terrible IMO. It seems to be pitched at folks who don't know any better, so just showing that you can use 'source' like a kind of config parser without pointing out that it totally just executes code is pretty reckless.
I thought it was going to be something more like "here's a way to read KEY=VALUE lines into an associative array" (which is pretty easy, and can lead to all sorts of fun discussions/learnings about arrays in bash, subshells, whitespace/$IFS, etc)
